Create a clone tree ~/.snapshot/ with every subdirectory of ~ and every file hard linked. They can delete th originals and recover them from ~/.snapshot/. A monitoring daemon can ensure that all files created are linked in soon thereafter. The path is the same path plus /.snapshot/
Now, if you want to ensure you can recover even after an overwrite, you have to copy not move. If space is a problem, the .snapshot can be a zip file. The daemon can have a directory of cksum values or trust time stamps to decide what is new to save.
I have seen facilities where ther were N snapshots holding files for N prior days, so you can recover an old version.
